Blank (empty) page in TYPO3

There is a question that I see several times monthly in TYPO3 mailing lists: "I see an empty (blank) page after XXX. How do I fix it?". Here is the step by step answer:

Go to the Install tool

Select "All configuration"

Set displayErrors to 2

Add your IP address to devIPmask

Now you will see PHP errors that happen. By default these errors are hidden by TYPO3 for security reasons and it causes blank pages. Changing settings above allows to see these errors on your IP address only.

So fix these PHP errors and your site will be back.

[Update: Feb 18, 2014] Alternatively you can check the web server error log for such errors. You can see something like:

I have just upgraded from typo3 4.2.9 and right after uploading the files and comparing the DB in the install tool, i was able to use the backend, because my session was still active.

However, after my BE session expired, I tried to login again. Unfortunately, the login page just displayes a blank screen. I cannot even see the username/password box. I did set the setting to Set displayErrors to 2 and added my IP, but the page is still blank. Yes, I deleted all files with temp_ and deleted the temp folders via the install tool as well. The FE works just fine.
